Abstrakt
ExCalibre is an online tool which enables users to automatically calibrate advanced soil constitutive models. It adopts a unique model-specific calibration algorithm respecting physical meaning of material parameters, rather than using a blind parameter optimisation.
It thus reproduces thinking of an experienced engineer calibrating the model, leading to a reliable parameter set to be used in geotechnical simulations. After calibration, the user can manually change the parameters to fine-tune the calibration or to investigate the effect of individual parameters on model predictions.
Simple Excel spreadsheet based on the provided template is used as an input. In addition to automatic calibartion, ExCalibre also acts as an element test driver simulating standard laboratory tests.
